      Answer This Question

      Yes, it can. However, a Galvanized Iron Pipe is a better option than a black steel pipe alone.

              The title states 2 in. for length, yet in the specs it says product length is only 1 in. What is the actual size, and does this include threads?

                After seeing some shelving ideas on Pinterest, I came across the plan to use the pipe as legs for a tiered shelving to hold the Lego creations for my son. The black pipe works great as it's not too big and allows me to keep the shelf within the size I wanted to but still strong to hold and support the wood. It's easy to cut with a pipe cutter we picked up from Home Depot. We used a steel brush and black spray paint to refinish the legs as black pipe isn't fashionable.

                Very effective for a natural gas line. The threads were all perfect with no imperfections. Threaded on smoothly using pipe sealer paste. Nipple sealed nicely between an elbow and a tee in a very tight spot. The pipe fitting had no issues passing the pressure test and so far has shown no deficiencies. I would recommend the Plumbers Choice brand for all your black pipe needs.

                Nice Heavy Black Pipe. We ordered these short black sections of pipe so we can build some industrial style shelving. We ordered lots of different sizes so we could have variable heights to the shelving. These are well made and very clean sections of pipe with no metal burrs or shavings. Its a nice heavy pipe and the treads work easily with all of our fittings and flanges. They are very affordable and made excellent shelving. I'm sure they would work grate for the original intent of plumbing/gas as well.

                Great Quality Black Pipe. We ordered multiple sizes of this pipe so we could build some tables with shelves. All of the pipes were great quality, very heavy and exactly what we were looking for. I'm sure they would be great for plumbing as well but we used them for design projects. But getting multiple lengths we are able to easily make varying height shelves. The threads are well cut without any metal shavings left behind. The screw into the flanges and other fits without issue. Awesome pipes.

                Well, the long story short is this, I only THOUGHT I had some form of "artistic leanings" in my gene pool. As it turns out, I ain't got talent in this. Story, I got all these pipe fitting on the Seeds program and thought I could make some cute little items like I've seen on other social sites. My mind just can't figure this one out!!! So far I've "made" a goal post like object and a book leaner upper thingy and thats about it. I KNOW now the artistic gene in me has "left the building"!!!!!!!!!!!!!!!!!!!!!

                I buy these iron products in bulk packaging as they are shown here. Purchasing them in this way makes them more affordable for me. This is important to me because, as a craftsperson, I use them in non-traditional ways. I have used iron (and brass and copper) pipes, nipples and fittings to make furniture, shelving units and lighting. Because of this it is important to make sure that the product is cleaned well. Removing the oily surface treatment is essential to creating products for home use. I hope you find this info helpful.
